Windows NT blocks direct access to ports, you have to use a suitable driver DLL - there are a number of free alternatives, you can download the one I use on the WinPicProg page.

That's just a little utility you can use to test the driver. There should be VB and VC code examples in the dlportio folder.

I've always wondered how windows 2000 & XP block direct port calls. I guess it's the protected mode kernal.

NT+ allows direct access to h/w ports to those only at 'ring0' level (where core os and device driver exist)
